1992～1994年,在浙江马尾松林里进行昆虫及蜘蛛群落、松毛虫天敌和种群动态的研究,结果查明:①15年生马尾松针叶立体分布,确认砍枝取薪以留7轮为好,不低于留4轮;②马尾松林昆虫群落分属18目118科,其中直翅目、鞘翅目、同翅目、膜翅日、半翅目占优势,经测定,龙游县群落结构复杂、分布均匀,群落与层次、坡向、郁闭度、灌层盖度关系密切;③蜘蛛群落分属19科46种,其中蠨蛸科、猫蛛科和蟹蛛科占优势,经测定,冠下层比冠层蜘蛛群落结构复杂、分布均匀,群落与松林不同层次、郁闭度、海拔、坡向等因子关系密切;④松毛虫寄生性天敌:卵期7种,寄生率12.24％,幼虫期7种,寄生率5.83％,蛹期14种,寄生率主3.790％。天敌与松毛虫虫口密度密切相关。采取以营林措施为基础的综合治理方法,改变了马尾松毛虫周期性猖獗现象,14年的综合治理,取得了显著的效益。
From 1992 to 1994, insect and spider communities, natural enemies of pine caterpillars and population dynamics were studied in Pinus massoniana forest in Zhejiang Province. The results showed that: (1) The three-year-old Pinus massoniana cones distributed in three dimensions, Lower than the remaining 4 rounds; ② Pinus massoniana forest insect community belonging to 18 orders and 118 families, of which Orthoptera, Coleoptera, Homoptera, Hymenoptera, Hemiptera dominated by the determination of Longyou County community structure is complex, The distribution of the community is closely related to the level, aspect, canopy density and canopy cover. The spider community belongs to 19 families and 46 species, of which 40 families are predominant, The structure of spider community in the lower layer was more complex and distributed than the canopy. The communities were closely related to different levels of pine forest, such as canopy density, elevation, slope aspect and so on. The parasitic natural enemies of the pine caterpillars: 7 species of eggs and 12.24% of parasitism. 7 species, parasitism rate 5.83%, pupal stage 14 species, the main parasitic rate 3.790%. Natural enemies and the density of pine caterpillars are closely related. Adopting the comprehensive management method based on silviculture measures, the phenomenon of periodic rampant of Dendrolimus punctatus has been changed. After 14 years of comprehensive management, significant benefits have been achieved.
